Hannah and Tyler, hope you are able to get your AC working again. The basement mounted unit must be very quiet.  There are at least 2 oddball Foretravels in existence now yours and mine.  I wanted to post a link to what I did but do not know how.  Search the forum for 1996 U270 Dual Central Air Conditioning.  What I did will not help with your problem.  I agree with what Tom said about relays, capacitors, thermostats, etc.  A good AC tech should be able to get it going if you can not find a board.  In case anyone is wondering my setup is still working, only trouble was a capacitor that needed to be replaced.

We took a few days off, now we're back at it!  Going to be doing some research on some of the suggestions of building something to control the unit without the board.  Got a friend who understands the electrical a lot better than I do to help.  There's a good chance it'll go nowhere but it sounds really interesting!

Haven't heard anything in a while from Hannah & Tyler.  Hoping they will see this, and update their progress (I assume) in getting the basement A/C fixed.  Always hate to be interrupted in the middle of a gripping good yarn, and then never find out the ending.

Hey guys,

A guy on the Newellgurus site contacted us and offered to build a board for us if we'd test it out and give feed back.  He is trying to create a permanent solution for his fellow Newell owners and we'll be able to beta test for him.  Hopefully that all works out, in the mean time we've replaced our entry door exterior latch and installed a trik-l-charge in the engine compartment and we were wanting to have our patio awning replaced but changed our mind after we got the estimate $$.  I went back to work for a while since the house hasn't sold yet, and haven't had much of an opportunity to do much work on the place.  I apologize for letting the ball drop on this thread but we haven't really made much headway.  We do appreciate the continued interest though so thank you for that.

The guy that was helping us with the circuit board emailed me this morning to let us know that Newell Coach had finished making their replacement boards for the RVAC 2702 .  I called Newell this morning and they explained how they had the board reverse-engineered to function and appear very similar to the old SCS boards but that they had fixed the weaknesses found in the original and they have already replaced several of their clients old boards with the new version without issue.  They had five left in stock so we ordered one before they ran out, cost for the board was around $632 after tax.  We are from Miami, Ok where Newell Coaches are made so I had my mom grab it today and hold it until we get back to the area in Feb.

We have air conditioning again! 

We got back to the tulsa area on Saturday, picked up the new board on Sunday and got it installed yesterday.  The project went smoothly, Newell did an excellent job of making the new board user friendly.  It took a little longer to install than it could have only because I cut out all of the old janky taped and wire-nut splices in the thermostat loom and soldered all of the joints together.  Other than the soldering it was really just plug-and-play.  That being said, I was still a bit nervous flipping the breakers on for the first time haha but there was no flames and everything worked just like it should.  We've got a new Coleman  6636-3441 thermostat on order to replace the slightly burnt original.  After that's installed we'll be good as new!

Glad to hear you found a solution to your problem, and although the board sounds expensive, maybe the cheapest solution after all.

We called the Newell plant in Miami, Oklahoma and ordered one.  Older Newell coaches had the same setup and there were no more boards to be had, so they had some new ones made up with beefier components and better design.

That's great news! Glad you checked and found a good solution.
